MRI

Magnetic resonance imaging (MRI) is a test that produces very clear pictures, or images, of the human body without the use of x-rays. MRI uses a large magnet, radio waves and a computer to produce these images.

Patients with the following medical devices can be safely examined with MRI:

Claustrophobia (fear of closed or narrow spaces). Please note: if this condition applies to you, Some patients may be candidates for sedation as long as prior arrangements have been made to the exam.

Allow 2 hours for your MRI exam. In most cases, the procedure takes 40 to 80 minutes, during which several dozen images may be obtained.

Before the exam

Personal items such as your watch, wallet, including any credit cards with magnetic strips (they will be erased by the magnet), and jewelry should be left at home if possible, or removed prior to the MRI scan. Secured lockers are available to store personal possessions.

During the exam

You will be asked to wear a hospital gown during the MRI scan.

As the MRI scan begins, you will hear the equipment making a muffled thumping sound that will last for several minutes. Other than the sound, you should experience no unusual sensations during the scanning.

Certain MRI exams require an injection of a contrast material called gadolinium. This helps identify certain anatomic structures on the scan images.

Please feel free to ask questions. Tell the technologist or the physician if you have any concerns.
